The efficient uptake or catalytic degradation of toxic chemicals is needed to provide efficient protection for both individuals and the environment. Herein, we report the benign synthesis of a Zn–azolate metal–organic framework (MOF) known as MFU-4l using ethanol (EtOH) as a solvent, which is efficient in the hydrolysis of an organophosphorus chemical warfare simulant (dimethyl-4-nitrophenyl phosphate, DMNP). Impressively, EtOH-derived MFU-4l hydrolyzed DMNP with a half-life of 0.5 h using only 6 mol % catalyst. Further postsynthetic modification of MFU-4l yielded MFU-4l-(OH), which exhibited high affinity for NH₃ with a steep uptake at a lower pressure (0.1 bar) as compared to the parent material (0.22 bar). Beyond the postsynthetic diversity inherent to the MOF, the benign synthesis of the active catalyst and sorbent render MFU-4l as a promising candidate for the removal of toxic chemicals.

用于增强氨吸收和催化水解有机磷化学品的 Zn-Azolate 金属-有机骨架的良性合成和改性

需要有效吸收或催化降解有毒化学品，才能为个人和环境提供有效保护。在此，我们报告了使用乙醇 (EtOH) 作为溶剂，良性合成了一种称为 MFU-4l 的锌-唑盐金属-有机骨架 (MOF)，该方法可有效水解有机磷化学战模拟物 (二甲基-4-磷酸硝基苯酯，DMNP）。令人印象深刻的是，EtOH 衍生的 MFU-4l 仅使用 6 mol% 催化剂即可水解 DMNP，半衰期为 0.5 小时。MFU-4l 的进一步合成后修饰产生 MFU-4l-(OH)，其对 NH ₃表现出高亲和力与母材 (0.22 bar) 相比，在较低的压力 (0.1 bar) 下具有陡峭的吸收。除了 MOF 固有的合成后多样性之外，活性催化剂和吸附剂的良性合成使 MFU-4l 成为去除有毒化学物质的有希望的候选者。
